Abstract

In an electrostatic development apparatus, drum 12 rotating on shaft SH-1 is changed by a corona discharge device 14 and a latent image is formed on the drum by lens 10, the drum then passes through a developer station A, a transfer station B and a cleaning station C. At the developer station A, toner T is blown on to rotating brushes 28-30 by a fan unit 31 which causes the toner powder to circulate from sumps 26 through conduits 32, 33 and back into the housing 26. Each brush comprises a hollow conductive cylinder 38 mounting bristles of rabbit fur or dynal, the three brushes being supported on mandrels 35-37 splined on to pulleys 42-44 driven by a motor 7. Axial movement of the shafts is achieved by the inter-position of wobble plates 48- 50 between the mandrels and the pulleys. This lateral movement of the brushes aids the formation of powder clouds to facilitate the developing process. At station B the image is transferred to web P by a corona discharge 23 and at 25, the developer material is fused to the web. The drum 12 is cleaned at C by a further corona discharge device, brushes 26 and a lamp.
